Manufacturing of nanostructured titanium Grade2 using caliber rolling

Krzysztof Topolski , Halina Garbacz

Abstract

In this paper, a new method of manufacturing nanostructured titanium (n-Ti) is presented. An effective way of grain refinement and strengthening a material using conventional plastic working is proposed. Microstructured titanium (m-Ti) Grade2 was processed using caliber rolling technology. In this work, the m-Ti billet in the initial state was in the form of a rod with a diameter of 10 mm. This billet was subjected to multi-pass longitudinal cold caliber rolling, during which the transverse section of the rod was gradually reduced. The rolling was carried out in such a way as to accumulate a relatively large plastic deformation in the workpiece. The rolling process resulted in a refinement of the microstructure into a nanostructure. The average grain size of 74 nm and enhanced mechanical properties were obtained. This single-phase Ti Grade2 with a nanostructure exhibits mechanical properties typical for titanium alloys. The results of the research confirmed that the technology used in this work makes it possible to generate a heavy strain enough for the purpose of grain refinement.
